This position is perfect for a couple who are bored to have sex in the bed. Fitness ball can be comfortable ad well. The woman lies on her back on the fitness ball, slightly leaning back, and supports herself by the hands placed apart. She bends her legs at the knees, lifts and drives them as wide as possible. The man stands between the hips of his darling, resting his knees on the ball. He leans forward slightly, outstretches arms and sticks his hands under her back.
